Hi Stinius,
I don't think I owe anyone any explanations or apologies. I tried to work with roender in the beginning, presented my ideas on his thread and he was not open to it.
It's not hard to track down the history here.

I have just had another look at Post #71.
Actually, the 3rd is slightly higher than the 2rd (both less than -100db), and the 4th order and higher harmonic artefacts are all below -125db ... that's quite stunning and did I say real nice, really real nice

Hi Pete,
If you had an email button I would have sent you a note.
I appreciate all of the help I have gotten on the many projects I have done since coming here. It should not be overlooked that this is a DIY site where we all are supposed to design, build and learn. I don't think I'm overstepping my bounds here by saying that I have given back as much or more than I have taken from here.

Now I tried to put a bit of a humorous spin on the situation here, but I can see that it went right over your head. As usual.

We are all different, I know. My reaction to someone wanting to take one of my projects and change it or improve it would be one of interest and enthusiasm. I wouldn't feel threatened by this. I wouldn't say: "do what you want, but don't refer to it in the same breath as mine". I'd feel flattered and vindicated that something that I did here made some difference.

I will have to take the plunge and board this up so that I can test it. The simulator does a good job of pointing in the right direction but the truth comes out in the real thing. I think the THD figures are close to accurate, but I don't put a lot of faith in the distribution on the harmonics. I think the simulator is just "guessing" there.
Still, low is low and better than high, right?

That popped into my head while I tried to think up a name for the sim file. Fits with the theme I think.
Anyway, tis too late - I've already busted a champagne bottle on her bow...

You have a way of dropping insults, it went over my head?
It is said that there is always some truth in humor, and it is your underhanded way of continuing to annoy him because you didn't like his reaction. There are much bigger things in life - get over your dislike of his response. You could simply respect his wishes and get out of his thread quietly without drama. Which I will now do with yours - not worth the time.

Enjoy your hacking and patchwork, but do the forum a favor and stop deliberately annoying people who have made significant positive contributions.

You say you appreciate the help that you've gotten, talk is cheap, I judge people by their actions.

Please don't email me.

Pete B.

By roender - Besides the fact that you have some mistakes in the schematic, the main two issues are related with highly asymmetrical clipping and headroom.

This is what "got me on the run" .. to explore how
your amp and mine handles mild and gross clipping.

The abomination does the best, it has less gain , just asymmmetric as noted above (just a little sticking)..livable .Mine sucked when overdriven.(both asym. and "sticks"... saturation)
First I thought it was the design..nope

Are the 2SA1381's really warranted though

It was the 1381/3503's ,these devices EXCEL in normal
operation.. but when they saturate, they really stick hard.
So , I resimmed mje 340/350's.. bang, fixed the problem.
also, if you put a .1uf cap across the Re of the CM so even
spikes from near saturation are gone..

In your amp (abomination) I just had to adjust Re's on
the VAS cascode to get symmetric clipping ,added that .1u cap
(your V- CM is the same as mine) all your cascodes helped
prevent saturation for the most part.
